Application led April 22, 1925. Serial No. 24,942.

'Ihe object of this invention is to provide a traction shoe particularlyadapted for use on a frozen surface, such as ice and which shall havemeans to dig into the ice, or the like, to eiectually prevent slippageand which shall at the same time be cheaply and efficiently made andshall be rugged in char-` acter so as to resist wear of all kinds.

In the accompanying drawing in which I have shown a selected embodimentof my in ventionz' Y Fig. 1 is an elevationl of a wheel having myimproved shoe attached thereto, and showing the shoe in section.

Fig. 2 is an outer plan view of the .shoe and Fig. 3 is a side elevationtaken onthe line 3 3 of Fig. 2.

Referring now to the drawing, the numeral 1 designates the rim of awheel of any suitable construction, but shown herein as carrying theteeth 2 toco-operate with l the ribs 3 and transverse bar 4 of the shoeto form a driving engagement therewith. In this embodiment the shoe isloosely held on the wheel by the holder 5 loosely engaging` thetransverse bar 4. j

Referring particularly to Figs. 2 and 3, it will be seen that myshoecomprises a plurality of longitudinally extendingribs 6, 7, 8 and 9,these ribs being provided adjacent their ends with projections 10.Vilhile I have shown these projections adjacent the ends, it is to beunderstood that they may be conveniently provided at any part of the ribwhere it maybe found to be desirable.

Connecting the ribs are a plurality of transversely extending webs 11and 12. The webs 11 extend between the ribs 6 and 7 and 8 and 9respectively and it is seen that they are in alignment with each otherand that the central webs 1l are also in alignment with the transversebar 4 and form in effect an extension of the bar so that it extendsentirely across the shoe. The end webs 11 may, if desired, be extendedoutwardly at one side of the shoe, as shown at 11 and join thelongitudinally extending ribs 13, which `are also provided withVprojections 14. The transverse webs 12 are preferably offset from thewebs 11, and by this means a stronger structure is provided in that,instead of having one continuous web 11 of a comparatively long span,three webs of short span are provided. Short longitudinal ribs 15connect the webs 12- with the edges of the shoe, and have projections 10at their intersectionsiwith the webs.

As will be best seen in Fig. 3 the transverse webs are provided withprojections 16, the highest points of which coincide with the highestpoints of the projections 10, or

lin other words, the webs and ribs are pro- By adopting this form. Imake it possible tol extend the shoe a substantial distance beyond theedges of the rim, as shown in Fig. 2 without danger of breaking orbuckling.

I am aware that changes in the form, construction andarrangement ofparts rmay be made Without departing from the spirit and Vwithoutsacrificing the advantages of the invention and I reserve the right tomake all such changes as fairly fall within the scope of the followingclaims.

I claim:
